Louisiana authorities stripped Explo Systems of its state explosives licenses on May 20, ABC News reported[2].

Authorities said they suspended the explosives recycling company’s license because it improperly stored millions of pounds of a military propellant. An explosion in October 2012 led authorities to investigate the facility and evacuate the nearby town of Doyline, Louisiana.

During the initial investigation, authorities found a M6, a propellant chemical, stored improperly. The chemical was stored in boxes in long corridors connecting several buildings, though it should have been stored in certified magazines. Authorities said some of the containers had spilled open.

Authorities put Doyline residents under a voluntary evacuation order in December due to the possibility of ignition of the propellant, which could have blown up multiple buildings.

Louisiana police have since monitored the proper storage of more than 10 million pounds of M6–a process which took several months.

Explo Systems has given up its keys to magazines at the facility.

The company was cited in 2007 for violations in West Virginia for its use of an old military explosive for coal mining.

The company has not been charged with any crimes. The investigation is still ongoing.
